The strong accents/marcatos should have more of a staccato and accent to them. There should be falls. Glissandos for trombones should make a smooth sound rather than playing all the notes in between. Allow arpeggios to be for both hands for the piano. The brackets should be pedal down too. In addition, there should be una and tre corda. There should also be changing pedal. And the mordents and turns and their inverted versions should be played, too.
